COFFEE-POT.

SPECIFICATION forming part of Letters Patent No. 573,440, dated December22, 1896.

Application iiled July 15, 1896. Serial No. 599,275. (No model.)

,To all whom t 11m/y concern:

Be it known that I, CHAELEs- H. CHAsE, a citizen of the United States,residing in Newport, in the county of Newport and State of Rhode Island,have invented new and useful Improvements in Coffee-Pots, of which thefollowing is a specification.

This invention relates to a novel construction and arrangement of partsfully described below, whereby the water is passed very slowly throughthe coffee and in such passage is sufficiently cooled to preventboiling, and hence becomes thoroughly impregnated.

The nature of the invention in detail is fully described below andillustrated inthe accompanying drawings, in which Figure l is a centralvertical section of my improved coee-pot. Fig. 2 is a 'view of thedetachable perforated disk removed. Fig. 3 is a view of thecoffee-holder removed.

Similar letters of reference indicate correspending parts.

A represents the main body of the coffeepot, provided with the usualcover A'.

B is a downwardly-inclined partition or flange extending inwardly fromand `with its outer edge resting upon the horizontal corrugation or stepd, formed in the body A. Rigidly secured to or integral with the inneredge of the partit-ion B is the tapered ring C, provided with suitableperforations C. The partition B divides the Water-chamber D from thedecoction-chamber E. Resting by means cylinder F, while the lowerportion of the4 tapered ring supports, by means of its shape, thecone-shaped coffee-receptacle H, whose bottom H is provided withperforations 7L. Resting in this coffee-holder H, by means of its flangeor rim K', is the removable perforated disk K, provided withperforations 7c, and having its sides or iianges K formed to correspondwith the tapered sides of the coffee-holder H. The periphery of the diskK is notched at K" in order to let said disk down by the inwardprojections L, secured to the inner surface of the coffee-holder, whenva slight turn of said disk locks it under said projections. A handle Pextends up centrally from the disk K to a convenient height within thecylinder F.

The coffee having been placed in the coffeeholder H and the partsarranged in the position indicated in Fig. l, water is poured into thechamber D, from which it passes through the perforations C in the ring Cinto the chamber above the disk K, thence through the pcrforations la insaid disk into the coffeeholder H, and thence it percolates slowlythrough the coffee and through the perforations h in the bottom H intothe decoctionchamber E. This is a comparatively slow process, takingusually from four to six minutes. Hence the water not only becomesthoroughly impregnated, but while passing from the chamber D through theperforations C and 7c has time to cool sufficiently to prevent anyboiling at the time it reaches the coifee. It is Well to remove a cupfulfrom the chamber E and return it to the coffee-pot after the processabove described.

To remove the grounds, the coffee-holder H can be lifted out by means ofthe handle P and the disk K, whose edges lie under the projections L. Itwill be seen that said disk and coffee-holder and the cylinder F are alleasily removable for cleansing purposes.

The relative sizes of the perforations h, C, and 7c are such as tosufficiently retard the progress of the water to and through the coffee.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is-- Theherein-described improved coifee-pot, comprising the ordinary sides A 5the downwardly-inclined inward partition B provided on its inner edgeswith the tapered perforated ring C and supported by said sides; thecylinder F supported by said ring, said cylinder, ring and partitionconstituting,with the sides of the coffee-pot, a separate water-chamber;the cone-shaped coffee-holder H supported in and by the lower portion ofthe ring C and provided with the perforated bottom H; and the perforateddisk K resting in and supported by the upper portion4 of the sides ofthe coffee-holder H and provided with` the handle P extending into thecentral cylinder, substantially as described.
